OPSMN-2358: Ensured the aggregate and reporting options are initialised when the
user quits "define view" by clicking on "Done" button.

The problem was aggregate and reporting options were initialised whenever their
respective screens/steps were visited by the users. This meant when users quit
define view in the first step itself, the other 2 reporting options remained
initialised and thereby causing malformed query error.
